title: Indications for intraoperative frozen section in robot assisted radical prostatectomy: a pilot study.
abstract: BACKGROUND
  To evaluate indications for intraoperative frozen section (IFS) during robot assisted laparoscopic radical prostatectomy (RALRP) in our series.
  
  
  METHODS
  Prospectively documented 80 patients with prostate cancer (PCa) who underwent RALRP were evaluated between June 2010 and July 2012. Patients were divided into 2 groups according to whether systematically IFS was performed or not. Group 1 (n=66) consisted of patients on whom systematic IFS was performed, Group 2 (n=14) consisted of patients on whom IFS was not performed. All recorded data evaluated and statistical analyses were performed for determining indications and predictive factors for IFS during RALRP. All patients were operated by single surgeon and IFS, pathological assessments were performed by experienced uro-pathologist. Statistical significant p value was p < 0.05.
  
  
  RESULTS
  Mean follow-up was 15±6 (25-4) months. Pre-operative prostate volume in trans- rectal ultrasonography (TRUS) was statistically higher in Group 1 than Group 2 (p = 0.037). The other parameters were statistically similar in both groups. According to outcomes of our study IFS was a dependent factor for positive surgical margin. Additionally, the cut off value of prostate volume in TRUS for IFS was 55.5 cc for IFS.
  
  
  CONCLUSIONS
  Preoperative measured prostate volume in TRUS may be an indicator of IFS. Therefore, more accurate information may be given to patients with prostate cancer (Pca) before RALRP by using preoperative prostate volume in TRUS.
